Alabama football brought in record $103.9 million....

The business of athletics remains lucrative for the University of Alabama.

According to documents filed with the NCAA, the school's profit increased 13.1 percent in 2016 to $18.7 million.

Revenue was up 10.1 percent total with a considerable jump in football cash. Nick Saban's program had a profit of $47.7 million on revenue of $103.9 million (up from $95.1 million last year).

In all, football accounts for 63.3 percent of Alabama's athletics revenue. Men's basketball is next at 8.8 percent of the total income.

The biggest jump from 2015 came in the media rights category. Alabama made $42.4 million in 2016, up 21.3 percent from the previous year.

It all feeds into the still rising bank accounts of college athletics. In the past 11 years, Alabama's revenue has jumped 142 percent from $67.7 million in 2006 to $164 million in 2016.

To compare to Alabama's $18.7 million total profit, Auburn's athletics department reported a $15.2 million surplus. Auburn's $140 million revenue was a school record, as was Alabama's $164 million in income.
